  1. 16. PET and MRI of Prostate Cancer

    Författare :Catrin von Below; Håkan Ahlström; Cecilia Wassberg; Mauritz Waldén; Jens Sörensen; Michael Häggman; Joel Kullberg; Katrine Åhlström Riklund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; lymph nodes; lymph node staging; PET CT; MRI DWI; extended pelvic lymph node dissection; targeted biopsies; multi-parametric MRI; TRUS guided biopsy; multiple regression analysis;

    Sammanfattning : Prostate cancer (PCa) is the most common non-skin malignancy of men in developed countries. In spite of treatment with curative intent up to 30-40% of patients have disease recurrence after treatment, resulting from any combination of lymphatic, hematogenous, or contiguous local spread.

  3. 17. Monitoring of neuroendocrine tumor patients undergoing systemic therapies

    Författare :Olof Pettersson; Anders Sundin; Håkan Geijer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Therapy monitoring; NET; neuroendocrine tumor; computed tomography; CT; PRRT; 177Lu-DOTATATE; TGR; tumor growth rate; theranostics; DOTATOC-PET CT; Radiology; Radiologi; Endokrinologi och Diabetologi; Endocrinology and Diabetology; Oncology; Onkologi;

    Sammanfattning : Monitoring of neuroendocrine tumor (NET) patients undergoing systemic therapies is troublesome as biomarkers capable of detecting tumor responses have been difficult to establish. Changes in the sum of target lesion diameters are used to evaluate the effects of therapy according to the response evaluation criteria in solid tumors (RECIST 1.1). LÄS MER

  4. 18. PET in Prostate Cancer – Detection, Tumour Biology and Prognosis

    Författare :Naresh Kumar Regula; Jens Sörensen; Mark Lubberink; Irina Velikyan; Katrine Riklund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; 11C-acetate; 68Ga-PSMA-11; 18F-NaF; PET CT; Radiology; Radiologi;

    Sammanfattning : Prostate cancer (PCa) is the most common non-cutaneous malignancy in men and the leading cause of cancer-related deaths in Sweden. Despite the major advances, the current diagnostic modalities fall short of standards, specifically, precise localization required for effective management of the PCa. LÄS MER

  5. 19. Skull base meningioma : Surgical and adjuvant treatment with clinical and PET evaluation

    Författare :Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Meningioma; cerebellopontine angle; translabyrinthine and transcochlear approaches; facial nerve; steretactic irradiation; proton beam therapy; interferon- alpha; PET; 11C-L-methionine; 76BR-BrdU; Neurovetenskap; Neurology; Neurologi; Medicine; medicin;

    Sammanfattning : The treatment strategy for skull base meningiomas remains a controversial issue. Because of the proximity of these tumours to critical neurovascular structures, the risk for vascular damage and new cranial neuropathies postoperatively is significant. LÄS MER

  7. 20. Assessment of attenuation correction methods for quantitative neuro-PET/MR

    Författare :Joao M. Sousa; Mark Lubberink; Lieuwe Appel; Håkan Ahlström; Mathias Engström; Ivo Rausch; Radiologi Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; MRI; attenuation correction; 68Ge transmission; quantification; 11C-PE2I; MRAC; DAT; CBF; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Hybrid PET/magnetic resonance (MR) can provide physiological, functional, and structural information simultaneously, facilitating research in neurological disorders. For quantitative PET, correction for photon attenuation (AC) is necessary. LÄS MER
